CMC Features

The CMC provides the following multiple systems management functions:
• Enclosure-level real-time automatic power and thermal management:
– Monitors system power requirements and supports the optional Dynamic Power Supply Engagement (DPSE)
mode. The DPSE mode improves power efficiency by allowing the CMC to dynamically place power supplies in
standby mode, depending on the load and redundancy requirements.
– Reports real-time power consumption, which includes logging high and low points with a time stamp.
– Supports setting an optional enclosure Maximum Power Limit, which either alerts or takes actions, such as
throttling server modules and/or preventing the power up of new server modules to keep the enclosure under
the defined maximum power limit.
– Monitors and automatically controls cooling fans based on actual ambient and internal temperature
measurements.
